The Brazilian is concerned about his lack of first-team opportunities and believes a move away from Old Trafford will enhance his chances of featuring in the 2014 World Cup

Manchester United midfielder Anderson wants to leave the club at the end of the season due to fears that a lack of first-team football will put paid to his chances of playing for Brazil at the 2014 World Cup, Goal.com understands.

A number of South American clubs are interested in signing the 24-year-old, while Porto are also hoping to bring him back to the Estadio do Dragao on a loan deal.

United could even use Anderson as a makeweight in any potential move for Porto's highly-rated Colombian attacker James Rodriguez.

"Anderson is desperate to play for Brazil in 2014 and knows he needs some regular match time," a source close to the club told Goal.com.

"Sir Alex can't offer him the first-team football that he wants."

The Red Devils value the midfielder at between €18 million and €24m and would welcome a permanent sale, but do not envisage any of the interested parties being able to come up with the full amount.

A number of Brazilian clubs have used third-party sponsors to fund the signings of big-name players in recent years, most notably when Flamengo captured Ronaldinho from AC Milan in 2011.

But if that scenario does not materialise, United see a loan move back to Porto as the ideal situation for both club and player.
